help please with daikin unit
Hi , I am replacing a old daikin r22 system for a new r410a unit. On the front of the old unit is a box that cuts the power to the main contactor from a frequency signal. I'm not sure if it is on a time clock or connected to the fire alarm. I'm not sure how to wire it into the new unit.
old unit R250F7W1
new unit RZQ250C7Y1B
It has 4 wires
1 live
2 neutral
3+4 on the old unit pink wire was cut (from PCB to the live on the contactor)
